Hi, I m totally desperate now. As in the Ubuntu package repos is only the 1.09
Version in which mglGraph does not have a member "SetMarkSize" So I tried to
install build the version by myself. There i got the fault:
Hmm, interesting situation. I have only few comments.
You can use just gr->MarkSize=... in v.1.*.
It is a bit strange about building process. I have no idea about libGL.a??? it should be libGL.so (i.e. dynamic library if you are trying to use/make dynamic MathGL library). Are you sure that you have installed package like libgl1-mesa-dev?
Last part is really strange. Since, make process failed then MathGL from sources shouldn't be installed at all. So, yours code should use MathGL from repositories. But it couldn't find it (the same with UDAV)?! I.e. it looks as conflict of different MathGL versions installed/used at the same time. Are you sure what you don't delete (or move, or replace) MathGL in folder /usr/lib/ manually?
So, the possible solutions are.
Remove (purge) MathGL installed from repository and make the latest version from sources following standard instructions. Be sure that you install all required dev packages (like libgl1-mesa-dev).
Clear MathGL from sources. If you are tried to install it, then you may find some files at (sub-)folders /usr/local/... by default.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Thanks, now I got it working. I still do not know where was the fault, i
deleted all and installed libpng then everything worked. Now two more issues:
There is now one more typo in the description, in the newer version you have
changed the order of arguments in mglGraphFLTK::Window. Here, the char
(Windowtitle) comes before mglGraph.
The second one is the fact that SetMarkSize(...) or MarkSize=... do not change
anything. My solution for getting smaller marks is so far
gr->SetBaseLineWidth(0.001);
gr->Plot(y," .");
gr-> SetBaseLineWidth(1);
gr->Box();
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Yours mark is dot ('.'). Mathematically, its radius is zero :). But to make it
visible on the line (i.e. for line style "-.") I set its radius to be
proportional line width.
So, you can just change line width to change the size of dots (i.e. style "
.2" will produce 2 times large dots).

There is now one more typo in the description, in the newer version you have

Thank you for typo.
Yours mark is dot ('.'). Mathematically, its radius is zero :). But to make it
visible on the line (i.e. for line style "-.") I set its radius to be
proportional line width.
So, you can just change line width to change the size of dots (i.e. style "
.2" will produce 2 times large dots).
